This document applies to issues where FTP no longer functions after installing LANDESK Antivirus.
LANDESK Antivirus monitors port 21, in turn causing it to block active FTP.
There are two options to resolve this issue. First would be to modify your FTP setup to be passive.
If modifying the FTP setup isn't possible then we need to change on setting on LANDESK AV.
Do this open Agent Settings -> LANDESK Antivirus.
Then open the Protection section and click on settings under Monitored Ports.
Then locate the entry for FTP 21 and delete it.
Finally schedule a settings update to the client and test.
